Abstract
A button-type secondary battery includes an electrode assembly; a lower can having an accommodation space in which the electrode assembly is accommodated; an upper can coupled to the lower can to cover the accommodation space; a gasket sealing a gap between the lower can and the upper can and to electrically insulate the lower can from the upper can while being inserted into a coupled portion of the lower can and the upper can; and a first electrode tab including a first coupling part coupled to a first electrode of the electrode assembly and a second coupling part coupled between the gasket, which is disposed at the coupled portion of the lower can and the upper can, and the upper can. The second coupling part is coupled between the gasket and the upper can by a pressure generated when the lower and upper cans are coupled to each other.
